Anyone know how to make iso oil out of stems? How much stem you would need for a good amount? How to make hash out of stems? Etc.
Grind/chop them up. Put them in a jar, cover in 91%+ Isopropyl Alcohol; make sure the alcohol is covering the material completely. Put a lid on the jar. And shake vigorously for about a minute.
Strain into a pyrex dish. You can use a kitchen strainer for this, but I find woman's panty hoes work well. Now you just let all the alcohol evaporate off and scrape off your hash with a razor blade.
I'm not sure how much you'd need, it depends on how potent your stems are. But I'd think you'd want a couple grams at least.
